Investigation of diffusion time dependence of apparent diffusion coefficient and intravoxel incoherent motion parameters in the human kidney.

Purpose: To characterize the diffusion time (Δ) dependence of apparent diffusion coefficient (ADC) and intravoxel incoherent motion-related parameters in the human kidney at 3 T.

Methods: Sixteen healthy volunteers underwent an MRI examination at 3 T including diffusion-weighted imaging at different Δ ranging from 24.1 to 104.

Catalytic Activity of Cellulose-Supported Platinum and Palladium Nanoparticles for Allylbenzene Hydrogenation.

Platinum and palladium nanoparticles were successfully deposited on tunicate cellulose via the photodeposition or microemulsion deposition method. Evenly distributed, small and narrow-sized particles in the range of 2-3 nm were obtained for microemulsion-prepared cellulose catalysts. The photodeposition method led to larger particle sizes, broader size distribution, and occasional agglomerations.

Presentation of microstructural diffusion components by color schemes in abdominal organs.

Purpose: Development of a color scheme representation to facilitate the interpretation of tri-exponential DWI data from abdominal organs, where multi-exponential behavior is more pronounced.

Methods: Multi-exponential analysis of DWI data provides information about the microstructure of the tissue under study. The tri-exponential signal analysis generates numerous parameter images that are difficult to analyze individually.

The impact of depressive and anxious symptoms on quality of life in adults on the autism spectrum.

Quality of life (QoL) is lower in adults on the autism spectrum (AS) compared with typically developing (TD) adults. In this context, recent studies have examined the role of depression and anxiety in reducing QoL in AS adults. The aim of this study was to (1) replicate these findings of lower QoL and (2) assess the negative influence of depressive and anxious symptoms on QoL in an adult AS (N = 86) and TD (N = 87) German sample with a broad age range (18-70 years).
